Abstract: Techniques are disclosed for maintaining processing unit core affinity for fragmented packets. In one example, a service physical interface card (PIC) implementing a service plane of a network device receives fragmented and/or non-fragmented packet data for a traffic flow. The service PIC comprises at least one processing unit comprising multiple cores. A routing engine operating in a control plane of the network device defines one or more core groups comprising a subset of the cores. The routing engine assigns the traffic flow to a core group and a forwarding engine operating in a forwarding plane of the network device forwards the packet data for the traffic flow to the assigned core group. A core of the assigned core group applies a network service to the fragmented and/or non-fragmented packet data for the traffic flow, and the forwarding engine forwards the packet data for the traffic flow toward a destination.
